As the bar moves to the right, the 5 one or more electric solenoids, B B, or electrorack H on the bar operates the pinion K until magnets, and a movable slide, 0, having 011 the wing Y on post A stands at right angles I its inner side the rack or teethH and the dogs to the track. The solenoid B attracts the bar H until a stop, M, on the wheel comes in contact with a lug, N, in the bottom of the box, Fig. 2, at which time the last tooth P of the wheel K has passed the last tooth of the rack and the dog R. The dog R is pivoted and held against the shoulder l) by a spring, S, which allows the rack H to pass beyond the teeth in the wheel K, the dog R yielding to allow the teeth to pass, and then springing back into position again.

The cut-away part U of bar C presses against the last tooth P of the wheel and prevents the wheel turning back until the motion of the rack is reversed, when the dog R will engage with tooth P and turn the wheel in the opposite direction. In closing the switch the lever F is turned back again, breaking the circuit with spring T, bringing the pin E in connection with spring T again, completing the circuit with solenoid l again, which attracts the bar 0 and draws it to the left again, the rack ll turning the pinion K, revolving the post A, and bringing the wing Y parallel with the track again.

On the tender of the locomotive or on any of the cars a connection is made with the airpipe of the brakes, and a short pipe, 0, attached, terminating in a valve, (1', operated by a handle, Z, some twelve inches long, reaching down far enough to come in contact with the wing Y on the arm A. \Vhen the switch is opened by the movement of handle F, as above described, and the circuit is completed, the solenoid B, through bar H, moves the wheel K and post A so as to bring the wing Y at right angles to the track and in the path of the handle Z. As the cars come along, the handle Z strikes the wing Y, opening the valve (1 and allowing the air to escape from the air-pipe on the train, which, with the automatic brake, sets the brake and stops the train. Vith the straight air-brake a connection is made with the air-drum in such a manner that the movement of the lever Z allows the air to pass into the air-pipe on the train, setting the brakes.

The bar 0, instead of operating the wing Y through the pinion Z, can be made to strike a lever at either end and move the wing Y into and out of position; or the bar-itself may be arranged to strike the arm orhandle Z and operate the brakes.

'What we claim as new is l. The combination, with a device on the cars for setting the air-brakes, of the wing Y, rack H, and dogs R, operated automatically by the attraction of the solenoids, as and for the purpose set forth.

The rack H, the pivoted spring-dogs R, and the toothed wheel K, as and for the purpose set forth.

3. The rack II, the pivoted spring-dogs R, the bevel U on bar 0, the toothed wheel K, the stop M, and the lugs N, as and for the purpose set forth.

4. The bar U, the rack H, the dogs R, and springs S, as and for the purpose set forth.
